Nitrogen-doped graphitization Multi-walled carbon nanotubes MWCNT

Nitrogen doping is a key modification in the study of carbon nanomaterials. For materials such as fullerenes, carbon nanotubes, and graphene, nitrogen doping can change the atomic structure of the edge or bulk phase of graphite carbon, thereby regulating its basic physicochemical properties.

In recent years, with the continuous development of chemical technology, the nitrogen-doped carbon nanomaterials have greatly enhanced the regulation of carrier density, surface energy and surface reactivity, thus broadening the application fields of materials.

Configuration-selective nitrogen doping is critical for the application of carbon nanomaterials in energy catalysis and storage. Through a simple liquid phase reaction, nitrogen-doped carbon nanomaterials can be synthesized by weak intermolecular interactions such as electrostatic force, redox potential difference, van der Waals force, etc., including polymers, transition metals, and metal oxides. Materials/nitride/sulfide, semiconductor quantum dots, etc., have good application properties in catalysis, energy storage, organic photovoltaic, OLED, etc. In addition, the nitrogen-doped carbon nanotubes can be cut to form a graphene nanoribbon structure under electrochemical oxidation treatment, and can be precisely regulated by doping density, applied voltage, reaction time and the like.
